If I'm not misunderstanding POV-Ray's version numbering scheme, this is
a source code maintainance release with no changes in functionality.
See "https://github.com/POV-Ray/povray/releases/tag/v3.7.0.8".

Indeed it is. See "https://github.com/POV-Ray/povray/search?q=optimiz" (or
just grep in "unix/install.txt" and "unix/configure.ac" in the source
distribution).
